Through the pre quality planning, we have quality management system as the guarantee from the design and development of the products, the purchase of raw materials, the storage and production, to the inspection, packaging and transportation of the finished products.
At the same time, we have our own physical and chemical laboratory, each batch of incoming materials are tested and analyzed to ensure that each batch is of high quality raw materials.
In the process, we imported high precision measuring and testing equipment, and established metrology testing room to ensure the accuracy of process measurement.
Automatic controls specific to our products have been developed and implemented in the manufacturing process:
1. noise control (multi-frequency and peaks),
2. structure control of the material,
3. crack detection
4. detection of micro burns for inner and outer rings.
Our process includes measurement by means of eddy currents, to determine microcracks and hardness in the rollers.
